I'll try to figure out how to put this in my signature when I'm on my computer. I have an Intex above ground pool 12 by 36 1779 gallons. pump I believe is cartridge 530 gallons per hour. it gets sun from morning till about 5 pm. It's about 70 degrees outside today. Test results are from the sticks because that's all I have until I get my new kit. Test results: TH 0 FC 0 PH 7.2 TA 80 CYA 0-20. These tests are as of right now. I'm using the BBB method. I put 2/3 the recommended CYA that I got from the pool math calculator to slowly build up my CYA using the sock method yesterday and ran the pump. Squeezing the sock a little from time to time. Today the sock is empty. I did slam the pool using bleach and recommended amounts twice in the last week. Question now is how much bleach should I be putting in until my CYA builds up? I've read that if chlorine reaches zero you need to slam it but since my CYA isn't doing it's job yet I figure I probably shouldn't be shocking it every night but what do I know, I'm a newbie. Set it up and filled it last week. Water is Crystal clear, with no junk in it.
